Which of the following options is NOT available in a two-tier employment model?

In a two-tier employment model, the management of employment relationships is typically more structured and defined. This model aims to simplify and clarify employee contracts and assignments, usually aligning them with specific organizational needs and compliance with employment laws.

The option stating "Unlimited Contracts" is not available in this model because a two-tier employment structure usually operates with constraints that limit the number of contracts an employee can have to ensure clarity and manageability. This model generally focuses on structured employment arrangements where assignments and contracts are explicitly defined and limited. Essentially, the two-tier model seeks to provide clarity and avoid confusion regarding the terms of employment.

In contrast, options like "Multiple assignment," "Multiple contract-Multiple Assignment," and "Single Assignment" more accurately reflect the flexibility and nature of employment relationships that can exist within the parameters of a two-tier system, where individuals may hold various assignments or contracts in line with organizational needs, yet still within defined limits set by the model.
